摘　　要：为了满足日益增长的分组数据业务需求,特别是下行业务需求,3GPP提出了HSDPA技术并进行了标准化。作为HSDPA的关键技术之一,HARQ能够自动适应瞬间的信道条件并且不太受测量差错和时延的影响。本文对采用不同方式HARQ的HSDPA系统性能做了较为详细的比较与分析并给出了最后的结论。In order to meet the growing demand for packet data services, particularly the need for downstream traffic, 3GPP proposed HSDPA technologies and make it standardized. As one of the key technologies of HSDPA, HARQ is able to automatieally adapt to the instantaneous channel conditions and is not subject to measurement error and delay. In this paper, the authors make a detailed comparison and analysis on the performance of HSDPA system under different HARQ schemes.
